A brief description of the use of Yipin
Mobile phone test card Test card (also known as white card) is used for signal testing in the communication industry. It is often used for mobile phones with comprehensive testers and self-built networks to test mobile phones. Interference-free comprehensive testing of mobile phones requires relevant signal testing of finished products during production, but large-scale screen display requires more manpower, material resources and testing time, making the production process complex and increasing costs. The test card can realize the only signal from the instrument to the mobile phone. The path makes the test environment more concise and solves this cumbersome problem. The test card can be used for coupling test, bit error rate test, etc. It is fully equipped and can be used for terminal and comprehensive tester testing.
2 Product Quality Assurance
Our company's test cards adopt special chips/compatible contacts produced by internationally renowned semiconductor manufacturers. The compatible design is suitable for all mobile phones and equipped with special systems. It fully complies with various specifications for mobile phone cards. Special semiconductors The silicon lining ensures that the card can withstand the pressure of Newtons per square meter. (The standard is Newtons per square meter.) It is suitable for use in industrial production lines and uses an ultra-long life to ensure that the number of reading and writing times is more than 10,000 times. (The standard only requires 10,000 times to be measured on a general production line. Each mobile phone is required to read and write times of 10,000 times. The patented chip protective layer ensures card security and prevents electronic attacks. The special card coating on the pressure-resistant card is anti-static and waterproof (hour immersion test). Special card body material (mixed high temperature It can withstand high temperatures and can work normally for more than 1 hour. Temperature shock test
Our company's products are authorized by the National Integrated Circuit Card Registration Center to use imported Samsung and other chips. The authorized scope is a contact card chip series]. All smart cards The physical properties, chemical resistance, and electrical properties of the contacts have all passed the inspection of the National Computer Quality Supervision and Inspection Center and the Card Quality Supervision and Inspection Center of the Ministry of Information Industry, providing authoritative quality assurance.
